Frequently asked questions
Everything you need to know about using BillSense.
Is BillSense free?
Yes, completely free to use. No account, no email, no credit card. If a retailer pays us a referral fee when you switch, we may receive that. We will never sort results by who pays us. Your best saving always comes first.
What states does BillSense cover?
We have full plan coverage for NSW, VIC, QLD, SA, and ACT. WA and TAS have limited plan availability in the AER registry, so results there may not be comprehensive. Northern Territory is not currently covered.
Can I compare gas bills as well as electricity?
Yes. BillSense supports both electricity and gas bills. Upload a gas bill and we will compare against gas plans in your state. Gas comparisons are available for VIC, NSW, SA, ACT, and QLD.
How accurate is the savings estimate?
The estimate applies your actual usage and billing period to every available plan in your network zone. It is as accurate as the data allows. Estimates assume your usage pattern stays the same on the new plan. Actual savings can vary if your usage changes, or if a plan has conditional discounts (introductory rates, loyalty discounts, pay-on-time benefits) that we cannot factor in from the AER data alone. Always verify on the retailer's site before switching.
Why are some plans not shown?
We only show plans that are available in your network zone (distributor area). Plans that require eligibility you haven't declared, such as solar, a concession card, or a business ABN, are hidden by default. You can turn these on using the filter bar on your results page. Some retailers also do not publish plans to the AER CDR registry, which means they won't appear here.
Is my data secure?
We extract only what we need: your energy retailer, tariff rates, usage, billing period, and state. We deliberately do not extract your name, address, or account number. The original file is never stored. We do not sell or share your data. See our Privacy Policy for full details.
Why does my plan show a warning about conditions?
Some plans in the AER registry show unusually low rates that are only available when you buy a solar or battery system from that retailer, or meet other specific eligibility conditions. We flag these with a warning so you know to check eligibility before acting on the saving.
The savings estimate looks very high. Is that right?
It can be. The AER comparison methodology annualises your billing period usage, so if you are a heavy user on a high rate, the gap to the cheapest plan can be large. Run the number past your last few bills to sense-check it. If the figure still looks right, it probably is. Energy prices vary significantly across retailers.
Why does BillSense show different plans to other comparison sites?
Other sites may receive referral fees that influence which plans are surfaced first. BillSense pulls directly from the AER registry and ranks strictly by lowest estimated annual cost. We do not accept plan placement fees. Plans that pay us referrals do not move up the list.
How do I switch plans?
Click the Switch & Save button next to any plan. You'll be taken directly to that retailer's sign-up page. You can also take the plan name and go to the retailer's website yourself. There is no obligation to go through BillSense.
How often is the plan data updated?
We fetch plan data live from the AER CDR registry each time you upload a bill. Retailers are legally required to keep this data current. We flag any plans not updated in the last 90 days so you can verify before switching.
Which states can compare energy plans on BillSense?
BillSense covers NSW, VIC, QLD, SA and ACT with full plan data. Upload your electricity or gas bill and we match plans to your exact distribution zone.
How do I know if I'm overpaying for electricity?
The fastest way is to upload your electricity bill to BillSense. We compare your actual usage and tariff rates against every plan in your area and show you the exact dollar difference in under 30 seconds.
